FAQ
Q.Is my content sent to a server?
No. All conversion happens in your browser. Your Markdown and HTML never leave your device.
Q.What Markdown flavor is supported?
GitHub-Flavored Markdown (GFM): tables, task lists, strikethrough, autolinks, fenced code blocks with language hints, and footnotes.
Q.Can I preview the rendered HTML?
Yes — switch to the Preview tab to see the Markdown rendered as it would appear on a webpage.
Q.Does HTML to Markdown preserve everything?
Most common elements convert cleanly. Very complex HTML with nested inline styles or custom elements may be simplified. The tool preserves headings, links, images, lists, code blocks, tables, and text formatting.
